DETAILED DESCRIPTION OF THE INEVNTION AND FIGURES
The present invention provides a unique and novel continuous liquid monitoring system adapted to continuously collect samples from a liquid system. The monitoring system of the present invention is adapted to be left in the system for a long time and to allow occasional collection of samples preferably from the last 24 hours. In any given time, the inspector collects the samples, which are samples from the last hours that are prepared to be taken to a laboratory. There is no need to make any preparations prior to the collection and the collection of samples is fully occasional. The inspectors are coming to the system in which liquid is flowing only to collect the samples from the last hours while there has to be no notice to the entity that is being inspected on the collection of the samples.
In accordance with an aspect of the present invention, the continuous liquid monitoring system of the present invention comprises a carousel provided with preferably 24 containers wherein each container is filled with liquid material in an interval of substantially 1 hour from the preceding container. In this way, the material from 24 hours of a day is being sequentially collected and monitored. In order to allow continuous monitoring without providing endless number of containers, the containers that are being used in the monitoring system of the present invention have a drain trap. Each container is provided with a drain trap that is adapted to allow drainage of liquid material from the fluid that is being inspected while a portion of the material is maintained in the container. The material that is being drained is material from a previous day while new material is being collected in the container. In this way, if 24 containers are being filled in interval of one hour between the containers, there will be 24 containers provided with liquid material from the last 24 hours at all times since material from the last day (25 hours) is being drained after 24 hours. The carousel can be computerized so as to begin sampling in a predetermined hour.
In another aspect of the present invention, the continuous monitoring system is an improvement of existing automatic systems in which a plurality of containers is received within stations in a carousel and sequentially filled with samples for 24 hours. In the improvement, the container is provided with a drain trap in the bottom portion so as to allow drainage of liquids that resides in the container when new material is being poured in the container. In the improvement, the carousel is provided with a cleanout adapted to drain excess liquids. Reference is being made to Figure 1 illustrating a container having a drain trap in accordance with a preferred embodiment of the present invention. Container 10 comprises a sample collection zone 12 and a drain trap 14. Collection zone 12 is provided with a receiving opening 16 through which liquid for inspection is being poured in. Drain trap 14 is provided with a spout 18 through which liquid is drained of the container. Opening 16 and spout 18 are provided with thread so as to allow a cover to be screwed on the openings when the container is being transferred to a laboratory.
When liquid is being poured into container 10 through receiving opening 16, the liquid is being drained through spout 18 until the height of the liquid is the same height as curve 20 on drain trap 14. The volume of liquid that is being received in the container is the volume that is received within the drain trap. When a new sample is being poured through receiving opening 16, the liquid that was received in the container is being drained through drain trap 14 and spout 18. The new sample rinses the container from the old sample. It is preferable and had been shown by the inventor that a new sample of volume that is substantially five times the volume of the sample that is being drained suffices in order to rinse any residuals from the last sample that is being drained so as to-allow accurate measurement of possible undesired elements in the liquid or to have accurate information on the composition of the liquid that is being inspected.
Each container is provided with a tag 22 that tags the exact identification of the material' in the specific container so as to allow the user to identify the exact hour of which liquid was collected to the specific container and its location. The identification parameters are preferably an identification number of the container, the number of carousel in which the container is provided and the identification of the monitoring system to which the specific carousel is linked. The identification tag enables monitoring the liquids that is being identified without computerized elements in the carousel itself.
Reference is now made to Figure 2a and 2b illustrating an isometric view and an upper view, respectively, of a continuous sampling carousel in accordance with a preferred embodiment of the present invention. A carousel 100 is provided with preferably 24 stations adapted to receive 24 containers 102.
Reference is now made to Figure 3a illustrating a cross sectional view of the continuous sampling carousel shown in Figure 2, provided with one container having a drain trap. Carousel 100 is provided with stations 108 that are designed to receive the containers. As mentioned herein before, the containers are adapted to drain; therefore, carousel 100 is provided with several cleanouts adapted to allow liquids that are drained of the containers to be spilled out of the carousel.
Returning to Figures 2a and b, each container is a container having a drain trap 104 such as the container shown in Figure 1. When carousel 100 is provided with the containers and is being operated to collect the liquid, robotic levers (not shown in the figures) pour the liquid from the monitored system into containers 102 through receiving openings 16. Each container is sequentially filled with liquid material preferably in an interval of one hour between the containers.
Reference is now made to Figure 3b illustrating a cross sectional view of the continuous sampling carousel shown in Figure 2, provided with a plurality
:of containers having a drain trap. Each container 10 is provided with a drain trap 14 adapted to maintain the last sample that was poured within the container.
It should be mentioned that any number of containers can be provided in each carousel and one can design a carousel that is adapted to receive a number of containers other than 24 wherein any other carousel is covered by the scope of the present invention.
The commercial continuous liquid monitoring system comprises also liquid pumping system provided with a hose adapted to collect the liquid from the system that is being monitored and filling hose that is mounted on a revolving lever that fills each container. The monitoring system is provided also with activation system and a control unit.
When a carousel is being taken to a laboratory for examination, another carousel is being mounted on the monitoring system so as to allow continuous collection of samples.
The continuous monitoring system of the present invention can be employed also in rivers or lakes to which sewage can be transferred. This can prevent pollution of other water resources.
It should be emphasized that the scope of the present invention is to monitor any liquid system in food industries, paint industries, chemical industries etc.
It should be clear that the description of the embodiments and attached
Figures set forth in this specification serves only for a better understanding of the invention, without limiting its scope as covered by the following Claims. It should also be clear that a person skilled in the art, after reading the present specification can make adjustments or amendments to the attached Figures and above described embodiments that would still be covered by the following Claims.
